I Had Resigned From My Last Company After A Fight With My Reporting Manager. Now, My Next Company Wants To Have A Background Verification And Do A Reference Check From My Last Boss. What Shou

This person should explain the entire situation to his/her to-be employer. Telling the truth, reasons and facts will bring in trust for the candidate to the new employer. Should explain everything with real and not manipulated facts, while also telling them that the earlier reporting supervisor will definitely not give a good feedback, and the new employer should try taking the feedback from someone else in the Company. What also he/she needs to keep in mind that what were the factors that generated the heat for arguments. If it was his/her fault due to which the argument started, then accepting the mistake even with the new employer and telling the truth is the only way to get out of this sin.

My advice to you would be to provide full disclosure to the HR of your current or prospective employer on issues you had with your previous manager. You can request them to reach out to your last organization’s HR instead of your manager for a reference check. You can also ask them to connect with your manager's superior or other senior people from your previous organization with whom you had a good working relationship with, to have a more all-round or balanced feedback. Also, in future, even if there is a lack of alignment between you and your manager, always try to leave an organization on a positive note, of course without compromising on your integrity.
